Recent rumors have suggested that the Samsung Galaxy S would be available on all carriers in the United States. While there’s still no confirmation for any carrier, a hands-on video from Howard Chui shows that T-Mobile is likely to be the first to get the phone.

Chui’s videos shows the Galaxy S running with several T-Mobile proprietary apps, including My Account and Visual Voicemail. Also supporting this theory is that the video shows a model number SGH-T959. Almost all Samsung phones that head to T-Mobile have a Txx9 suffix. This strongly suggests that T-Mobile will probably be the first network to carry the Galaxy-S.

The only other explanation would be that Howard loaded the phone with his own T-Mobile USA SIM and downloaded the apps. When I had my Sony Ericsson review unit, popping in my T-Mobile SIM instead of the AT&T SIM that came with it allowed me to load My Account, Visual Voicemail, and the App Pack. I think this is less-likely, however, because Howard is based in Canada and probably doesn’t use T-Mobile.
